Hi,
is there a way we can write an if/else condition rules??
below are the details what i am trying
RewriteCond Host: (.*)
RewriteRule .*/Corda/redirector.corda/([?@_]{3}[a-zA-Z0-
9]{5}[_][a-zA-Z0-9]{4}[_][a-zA-Z0-9]{4}[@_]{2}[A-Z]{17})?
http://$1/search.aspx [I,RP,U,L]
this rule works fine for all the url's mentioned below as
it satisfies the reg ex.
http://xyz.gov/Corda/redirector.corda/?
@_CPRIH_raPH_MOHK@_TEXTDESCRIPTIONEN
http://xyz.gov/Corda/redirector.corda/?
@_CPRMR_raPM_HNVX@_TEXTDESCRIPTIONEN
http://xyz.gov/Corda/redirector.corda/?
@_CPRSI_raPQ_d27v@_TEXTDESCRIPTIONEN
http://www.xyz.gov/Corda/redirector.corda/?
@_CPRHO_raRF_xyef@_TEXTDESCRIPTIONEN
if the url is not in that format , i need to redirect the
request to an error page.(in other words, any request
that does not match this format "corda/?
@_CPRIH_raPH_MOHK@_TEXTDESCRIPTIONEN" should be
redirected)
regular expression for matching the "corda/?
@_CPRIH_raPH_MOHK@_TEXTDESCRIPTIONEN" is "([?@_]{3}[a-zA-
Z0-9]{5}[_][a-zA-Z0-9]{4}[_][a-zA-Z0-9]{4}[@_]{2}[A-Z]
{17})"
any help would be greatly appriciated.

First, your rule is not completely correct.
The correct one is:
RewriteCond Host: (.*)
RewriteRule .*/Corda/redirector\.corda/\?@_[a-zA-Z0-
9]{5}_[a-zA-Z0-9]{4}_[a-zA-Z0-9]{4}@_[A-Z]{17}
http\://$1/search.aspx [I,RP,U]
Second, you could simply put the 2nd rule like:
RewriteCond Host: (.*)
RewriteRule .* http\://$1/error.aspx [RP,U]
after the 1st one. It will redirect anything that has not been matched by the 1st rule.

Hey Lexey,
Thanks for your response.
i added these two entries in my httpd.ini file as you
mentioned and now every request is redirected to error
page.
do i need to group these 2 rules? not sure if i am
missing anything
RewriteCond Host: (.*)
RewriteRule .*/Corda/redirector.corda/\?@_[a-zA-Z0-9]
{5}_[a-zA-Z0-9]{4}_[a-zA-Z0-9]{4}@_[A-Z]{17}
http://$1/search.aspx [I,RP,U]
RewriteCond Host: (.*)
RewriteRule .* http\://$1/error.aspx [RP,U]

Oh, sorry, that is my fault.
Either replace the the 2nd rule with:
RewriteCond Host: (.*)
RewriteRule (?!/search\.aspx).* http\://$1/error.aspx [RP,U]
or add the following rule before the previous two rules:
RewriteRule /search\.aspx.* $0 [I,L]

Hey Lexey,
Thanks !
one last question, i want a rewrite rule when matches
this format .*/Corda/redirector.corda/\?@_[a-zA-Z0-9]
{5}_[a-zA-Z0-9]{4}_[a-zA-Z0-9]{4}@_[A-Z]{17} should do
nothing.
i mean ,
RewriteCond Host: (.*)
RewriteRule .*/Corda/redirector.corda/\?@_[a-zA-Z0-9]
{5}_[a-zA-Z0-9]{4}_[a-zA-Z0-9]{4}@_[A-Z]{17}
DO NOTHING [I,RP,U].
in my earlier post i mentioned it wrong, it should not
redirect to serch.aspx when it matches the format.it
should only redirect to error page when it does not match
the format.
sorry about the confuiosn, above solution you provided
worked but even the urls that match the format are being
redirected, which is not the requirement.
our basic requirement is to filter any requests that
does not match the format and redirect to error page , if
it matches then do nothing(let the original request go
thru).
Thanks alot !!

The following pair of rules will do the job:
RewriteRule .*/Corda/redirector\.corda/\?@_[a-zA-Z0-9]
{5}_[a-zA-Z0-9]{4}_[a-zA-Z0-9]{4}@_[A-Z]{17} $0 [I,L]
RewriteCond Host: (.*)
RewriteRule .* http\://$1/error.aspx [RP,U]
